Here are some other observations that you can make about the radar graph.

• Eight of the countries experienced a large increase in the percent of 18-year-olds in school (more than an additional 10% in school). Those countries are the Czech Republic, Estonia, Hungary, Ireland, Latvia, Lithuania, Poland, and Romania.
• Sweden had the greatest percent of students enrolled in school in both 1998 and 2007.
• By drawing a circle at 90%, you can see that in 2007, Finland, Lithuania, Poland, and Sweden had more than 90% of 18-year-olds enrolled in school.
